[pdf] LiFePO4 (lithium iron phosphate) battery packs are rechargeable energy storage systems using lithium-ion chemistry with a phosphate-based cathode. They offer high thermal stability, long cycle life (2,000–5,000 cycles), and enhanced safety compared to traditional lithium-ion batteries.
[pdf] Retaining up to 80% of their original capacity, these batteries can serve 5–8 additional years in stationary applications. For clinics, schools, and agricultural sites, they can provide dependable storage at 30–50% less cost than new battery systems.
